Tips on removing the misfed paper
Note the following points in removing the misfed paper.
Remove the misfed paper carefully so as not to tear it.
To avoid tearing the misfed paper, remove the paper slowly with both hands. Using force may tear the paper, making
it more difficult to remove. See also that no pieces of torn paper are left inside the equipment.
When the paper misfeed sign remains after removing the misfed paper:
Depending on the timing of the occurrence, no misfed paper may be found where the paper misfeed sign indicates. If
the sign does not disappear after you have removed the misfed paper, follow the steps as instructed on the touch
panel.
Do not touch the connectors and harnesses inside the equipment.
This could cause a malfunction.
Do not touch the fuser unit or the metal portion around it.
Do not touch the fuser unit or the metal portion around it when you
remove the paper misfed in the right side of the equipment. This could
burn you or the shock could cause you to get your hand injured in the

TROUBLESHOOTING FOR THE HARDWARE
Clearing paper misfeeds caused by a wrong paper size setting
Paper misfeeds occur when there is a mismatch between the size of the paper in a drawer or the bypass tray and the
size registered for the corresponding drawer or the bypass tray in the equipment. The message “Check paper size
setting on control panel for drawer N. Check the direction or size of the paper.” or “Check paper size setting on control
panel for Bypass. Check the direction or size of the paper.” appears on the touch panel.
In this case, just clearing the misfed paper does not prevent another paper from being misfed. Be sure to follow the
procedure below.
Troubleshooting differs depending on how the paper misfeed has occurred.
Misfeed when making copies or prints (using a drawer)
1
Clear the paper misfeed following the guidance shown on the touch panel.
2
Open the paper source drawer, check that the guide width is correct and there is no folded/curled
paper or overloading, and then close the drawer.
Be sure that the height of the stacked paper does not exceed the line indicated inside of the side guides.
In particular, be sure that the upper limit for thick paper is not exceeded when placing thick paper in the first
drawer of the e-STUDIO2020AC/2520AC/2021AC/2521AC. The amount of thick paper you can load in the drawer is
lower than that for plain paper.

If you do not want to delete the print job
To restart the job without canceling it, replace the paper in the drawer with that corresponding to the size set in
the equipment after the paper misfeed is cleared. After that, press [Resume] in Step 4. The print job can be
resumed. In this case, it is not necessary to follow step 5 and later.

When Printed Sheets Overflow from the Exit Tray 97
TROUBLESHOOTING FOR THE HARDWARE
0.When Printed Sheets Overflow from the Exit Tray
When thin, small size paper (A4-R/LT-R or smaller) is used, the end of the sheets may get stuck in the exit tray walls. If
300 or more sheets are printed under such condition, some printed sheets may be pushed out of the exit tray.
In the case above, installing the paper exit stopper at the designated location of the exit tray will increase the amount
of recommended plain paper that can be loaded on to the exit tray to about 500 sheets.
When printing a large number of large size sheets such as A3 and A4/LD and LG, place the paper exit stopper back in
its original location.
When the finisher is installed in the equipment, use the paper exit stopper installed in its original location.
When the Job Separator is installed in the equipment, attach the paper exit stopper at the designated location of
the exit tray.
When a large number of large size sheets such as A3 are output to the exit tray of the equipment while the finisher is
installed, remove them in more than one time.
Removing the paper exit stopper from its original location
1
Unfold the paper exit stopper located on the left of the exit tray and remove it from its groove
while pushing the fulcrum inward.
Installing the paper exit stopper in the designated location for improving paper exit
1
Turn the tip of the paper exit stopper to the left and insert the paper exit stopper fulcrum into the
groove on the exit tray.
Placing the paper exit stopper back in its original location

98 When Paper Has Been Curled
0.When Paper Has Been Curled
If you use e-STUDIO2525AC/3025AC/3525AC, the output paper may be curled on the exit tray when printing of a large
number of sheets of thin and small size paper (A4-R or smaller) is performed. In such a case, remove the parts (“A”
indicated in the figure) from the paper exiting section of the equipment.
When printing of a large number of large size sheets such as A3 and A4/LD and LG is performed, return those parts (“A”
indicated in the figure) to their original location.
Removing the parts (“A” indicated in the figure)
1
Turn off the power of the equipment.
2
Remove the parts (“A” indicated in the figure) attached to the paper exiting section.
Keep the removed parts.
Returning the parts (“A” indicated in the figure) to their original location
